Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

RP200 V500R002C00, V600R006C00; TE30 V100R001C10, V500R002C00, V600R006C00; TE40 V500R002C00, V600R006C00; TE50 V500R002C00, V600R006C00; TE60 V100R001C10, V500R002C00, V600R006C00 have an out-of-bounds read vulnerabilities in some Huawei products. Due to insufficient input validation, a remote attacker could exploit these vulnerabilities by sending specially crafted SS7 related packets to the target devices. Successful exploit will cause out-of-bounds read and possibly crash the system.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

This CVE describes out-of-bounds read vulnerabilities in multiple Huawei video conferencing devices (RP200, TE30, TE40, TE50, TE60) across specific firmware versions. The vulnerability exists in SS7 (Signaling System 7) packet processing due to insufficient input validation. A remote attacker can send specially crafted SS7 packets to trigger the out-of-bounds read, potentially causing system crash.

MitigationApply Huawei vendor firmware patches for the affected versions. If patches are unavailable, consider network segmentation to limit exposure to untrusted SS7 traffic sources.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify the device model
    Access the device management interface or use 'display device' command to confirm the model is one of: RP200, TE30, TE40, TE50, or TE60
    Affected if Device model is not one of the five affected models, the system is not vulnerable to this specific CVE
  2. Check the firmware version
    Use the command 'display version' or access the device status page to retrieve the firmware version. Compare against the affected versions: RP200 (v500r002c00, v600r006c00), TE30 (v100r001c10, v500r002c00, v600r006c00), TE40 (v500r002c00, v600r006c00), TE50 (v500r002c00, v600r006c00), TE60 (v100r001c10, v500r002c00, v600r006c00)
    Affected if Installed firmware version exactly matches one of the listed affected versions
  3. Verify if SS7 protocol is enabled
    Check the device signaling configuration for SS7 (Signaling System 7) protocol settings. Use 'display ss7 configuration' or navigate to the signaling/telephony settings in the device web interface to see if SS7 is configured and active
    Affected if SS7 protocol feature is enabled and the device has an IP address reachable on signaling ports (typically port 2775 for SS7)

The system is affected only if the device model is RP200, TE30, TE40, TE50, or TE60 AND the installed firmware version exactly matches one of the vulnerable versions AND SS7 protocol feature is enabled on the device.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.

Mitigation

Apply Huawei vendor firmware patches for the affected versions. If patches are unavailable, consider network segmentation to limit exposure to untrusted SS7 traffic sources.
